This is from the Cake Mix Doctor's Chocolate book. Dark, rich, and no-fail since it starts with a mix.

  1. Place a rack in the center of the oven and preheat the oven to 350 degrees.
  2. Grease and flour a 9x13" cake pan.
  3. In a large mixing bowl, place the cake mix, sour cream, water, oil, eggs, and vanilla. Mix with an electric mixer on low for 1 minute.
  4. Stop the mixer and scrape down the sides of the bowl. Increasing the mixer speed to medium, mix for 2 more minutes, until the batter is well blended.
  5. Pour the batter into the prepared pan, smoothing the top with a spatula.
  6. Bake the cake for 38 minutes. It's done when it springs back when lightly pressed with your finger. It might need up to 4 more minutes, depending on your oven.
  7. Remove the pan from the oven and cool, in the pan, on a wire rack.
  8. Frost with desired frosting.

OH What a cake. I used rewgular chocolate frosting, and it was enjoyed. Fluffy, flavorful and tasty. I baked mine for 40 minutes instead of 38. Turned out well. Served with vanilla ice cream. Made for Potluck tag.
